PHP wordwrap() Function

The wordwrap() function is a built-in function in PHP. This function wraps a given string to a given number of characters using a string break character. Syntax:

string wordwrap ($str, $width, $break, $cut )

Parameters : The function accepts 4 parameters as shown in the above syntax and are described below:

1. $str: This parameter specifies the input string which is needed to break up into lines.
2. $width: This parameter specifies the number of characters at which the string will be wrapped. That is number of characters after which the string will break.
3. $break: This is an optional parameter and if specified appends the value at the point of breaking the string.
4. $cut: It is a boolean parameter, if this parameter is set to TRUE, then the string is always wrapped at or before the specified width. That is it will also break a word from between if it comes in middle of the constraint specified by the parameter $width. When this parameter is set to FALSE the function does not split the word even if the width is smaller than the word width.

Return Value: The function returns a string wrapped upto specified length i.e. the string broken into lines on success, or FALSE on failure. Below programs illustrate the wordwrap() function in PHP : Program 1 : php

<?php

// Input string
$str = "keep practicing at geeksforgeeks";

// prints the wrapped string
echo wordwrap($str, 15, "\n", TRUE); 

?>

Output:

Program 2 : php

<?php

// Input String
$text = "Be a part of geeksforgeeks.";

// Wrapped string
$newtext = wordwrap($text, 8, "\n", TRUE);

echo "$newtext\n";

?>

Output:

Be a
part of
geeksfor
